BACKGROUND OF INVENTION

[0002] Portable tool cases have long been used to store tools, enablingconvenient transportation and retrieval of tools from the case. Toolcases may also be used to merchandise sets of tools. A desirableattribute of such tool cases is that they are capable of displaying thetool set, so that a prospective customer can see the tools held by thecase. Tool cases typically comprise a storage area with a cover. Thestorage area may have a number of recesses where the tools are stored.These recesses usually have an overall shape that conforms to the shapeof the tool to be stored therein. An individual tool is placed withinits designated recess, fitting snugly therein so that it will not bedislodged unless manually pulled from the recess. To access the tools,the tool case should be below eye level so that the user can look intothe interior of the case. Often times, however, the tool case is abovethe eye level of the user, for example, when the user is working under acar, and the tool case is lying on a floor. To access the tools, theuser must move his or her body out from underneath the car, sit up, lookinto the tool case to find a desired tool, and then crawl back under thecar, where the tool is then used. Thus, it would be advantageous if atool case had a mechanism with which it could be orientated into adesired position, such as a position allowing a user to view the storagearea from a prone position. Moreover, it would be advantageous if thismechanism were a component part of the tool case. It would also beadvantageous if the tool case could also be used to display the tool seton a counter top or other location in a manner that allows a prospectivecustomer to see the tools within the case.

SUMMARY OF INVENTION

[0003] This invention has several features that are summarized in theCLAIMS. These features provide this invention with its many desirableattributes. After reading the following section entitled “DETAILEDDESCRIPTION,” one will understand how the features of this inventionprovide its benefits, which include, but are not limited to, providing aportable tool case that can be supported in a display, table and/oreasel position using the cover of the case as a support mechanism.

[0004] This invention has several features. Without limiting the scopeof this invention as expressed by the claims that follow, its moreprominent features will now be discussed briefly. After considering thisdiscussion, and particularly after reading the section entitled,“DETAILED DESCRIPTION,” one will understand how one or more features ofthis invention provide its benefits, which include, but are not limitedto, providing a portable tool case that is adaptable to displaycontained items and provides easy access to contents within. A featureof the portable tool case is a cover that may be used to support thecase on a support surface.

[0005] A first feature of this invention is that it provides a portabledisplay case capable of storing one or more tools. It includes a traybody and at least one cover member that is rotatable into one of amultiple of different positions or orientations, all of which functionto support on a substantially planar support surface the display case ofthis invention.

[0006] A second feature is that the cover member preferably has asubstantially rectangular configuration, a base side and a storage sideadapted to hold the tool or tools. The cover member is rotatablysupported on the tray body for manual movement through an arc that isequal to or greater than 270° to move the cover member from a closedposition where it substantially covers the storage side to a supportposition where the cover member and base side are at an angle of 90° orless. The cover member has a face surface that faces the storage sidewhen in the closed position, and when in a support position, rests on asupport surface. The cover member also has a first pair of opposed edgesand a second pair of opposed edges and is rotatably supported on thetray body by a coupling at one of the first pair of opposed edges. Whenthe cover member is in an alternate support position or orientation, oneof the second pair of opposed edges rests on a support surface.

[0007] Optionally, when in the closed position, the tray body and covermember may be latched together by a latch member capable of couplingtogether the tray body and cover member such that the movement of thecover member is prevented. Preferably, the cover member has atransparent portion and may be entirely transparent.

[0008] A third feature is that the cover member is rotatably supported ahinge element that is along an edge of the tray body. The hinge elementcomprises a cover hinge element integral with said cover member and atray hinge element integral with said tray body. Either one has twoinsertable portions and a cylinder extending between the two insertableportions, and the other one has two insert receivers and a slottedreceiver disposed between the two insert receivers. When the covermember is hinged to the tray body, each of the insertable portions areinserted into an insert receiver, and the cylinder is inserted into theslotted receiver.

[0009] A fourth feature is that the tray body has a plurality ofrecesses within, each having open mouths on the storage side. The openmouths have a shape substantially identical to the overall shape of anindividual tool to be retained in the recess.

[0010] A fifth feature is that the display case includes a removableinsert comprising an inserted portion and a lever portion. The insertportion is coupled to the tray body along an edge of the tray body byinserting the inserted portion into a receiver located near the edge ofthe tray body and the lever portion supports the tray body on asubstantially planar support surface.

[0011] In one preferred embodiment, the tray body has opposing edgesthat substantially define a first predetermined area of the supportside. There is a pair of substantially rectangular, equally sized covermembers attached to the tray body. Each one of the pair of cover membershas opposed edges that substantially define a second predetermined areathat is substantially equal to a bisection of the first predeterminedarea. Each one of the pair of cover members is rotatably supported by ahinge element that is along one opposing edge of the tray body. Thecover members each have an inner and outer edge, and each of the covermembers is rotatably supported on the tray body by a coupling at theouter edges. When the cover members are in one of the multiple supportpositions or orientations, the inner edges rest on a support surface.The use of the pair of cover members enables the display case to rest onthe support surface in one of three different orientations:

[0012] (1) An easel orientation support position where one of the covermembers projects outward from the base side and the face surface of thisone cover member rests on the planar support surface.

[0013] (2) A display orientation support position where one set of edgesof both cover member rests on the planar support.

[0014] (3) A table orientation support position where another set ofedges of both cover member rests on the planar support.

DETAILED DESCRIPTION One Embodiment of This Invention

[0032] As illustrated in FIGS. 1, 2, 5, 6, 7 and 8, a tool case 10 ofthis invention includes a tray body 20 used to store tools and a pair ofrectangular shaped cover members 12 and 14. The tray body 20 has arectangular shape defined by edges 26 a, 26 b, 28 a, 28 b, a storageside 24, and a base side 22, which may also be referred to as theunderside of the tool case 10. The tools are stored within recesses 11in the storage side 24; these recesses typically have a shape like thatof the individual tool stored therein.

[0033] The cover members 12, 14 cover the storage side 24 of the toolcase 10 and each are coupled to the tray body 20 through a hinge 18.Typically, the hinge 18 connects an edge 12 b, 14 b of a cover member toan edge 28 b, 28 a of the tray, respectively. Typically, the covermembers 12, 14 are approximately the same size, and cover the sameamount of area of the storage side 24 of the tray 10. The cover members12, 14 bisect the storage side 24 of the tray such that each covercovers approximately the same surface area of the storage side 24.

[0034] In one embodiment as best shown in FIG. 7, the one cover member12 has an overlay portion 12 a, while the other cover member 14 has anunderlay portion 14 a. The cover member 12 with the overlay portion 12 amay be referred to as the overlay cover, and the cover member 14 withthe underlay portion 14 a may be referred to and the underlay cover.When closed, the overlay cover 12 is laid atop the underlay cover 14such that the overlay portion 12 a is atop the underlay portion 14 a. Asbest illustrated in FIGS. 1 and 5, a pair of latches 16 are used to holdthe cover members 12 and 14 in position when these members closed.Typically, each latch 16 is attached at opposed sides of the overlaycover 12, and each latch 16 has flap 16 a connected by a hinge segment16 b to the overlay cover 12 a. Each latch 16 is manually coupled to thetray body 20 by moving a free end 16 c of the flap 16 a over lip portion40 on a side of the tray body 20. The latch 16 is kept in place byfrictional contact with the lip portion 40 of the tray 20. Thus, theoverlay cover 12 restricts the movement of the underlay cover 14, whenboth are in a closed position and latched together. In one embodiment, aportion of the cover members 12, 14 is transparent, allowing a user toview the tools stored within the tray body 20. Preferably, the covermembers are locked in a closed position prior to being sold. With thecover members 12, 14 closed as shown in FIG. 1, there are holes 60 and61 (FIG. 7) at opposed outer edges in these cover members that arealigned with holes 62 in the tray body 20. A wire type lock member (notshown) extends through these aligned holes 60, 61 and 62 to lock thecovers closed. This wire type lock member is severed after the case 10has been purchased.

[0035] Referring to FIGS. 6, 7, and 8, in one embodiment, the hinges 18for the cover members 12 and 14 are essentially the same. Each hinge 18has three hinge elements 17 a, 17 b, 17 c integral with, for example,the cover member 14, and three hinge elements 19 a, 19 b, 19 c integralwith the tray body 20. These six elements are connected together to formthe hinge 18.

[0036] The hinge elements 19 a, 19 b and 19 c are in alignment along acommon axis X and spaced apart to separate these elements to createthere between the spaces S1 and S2, which are each about the same lengthL1. Each of the hinge elements 19 a and 19 c have, respectively, atinside ends thereof receiver sockets 19 d and 19 e. The hinge element 19b has a hollow cylindrical configuration with a slot 19 f in a side wallof the cylinder forming the hinge element 19 b. This hinge element 19 bhas a length L2.

[0037] The two hinge elements 17 a and 17 c have a generally rectangularconfiguration. There is an outer hemispherical tip portion 17 dextending from an outside end of the hinge element 17 a, and an outerhemispherical tip portion 17 e extending from an outside end of thehinge element 17 c. Each hinge element 17 a and 17 c have the same widthw and fit snugly within the spaces S1 and S2, respectively, but are freeto rotate as will be explained subsequently in greater detail whenconnected with the hinge elements 19 a through 19 c. The hinge element17 b is a cylindrical rod extending between and integral with the insideends of the hinge elements 17 a and 17 c. This hinge element 17 b has alength L3 that is substantially the same as the length L2 of the hingeelement 19 b.

[0038] The hinge elements 17 b and 19 b are slightly flexible so thatmay be bent to facilitate connecting the other hinge element together toform the hinge 18. To connect the underlay cover 14 to the tray body 20the rod hinge element 17 b is bent outward and the opposed hemisphericaltip portions 17 d and 17 e are inserted into the receiver sockets 19 dand 19 e, respectively. The rod hinge element 17 b is straightened andinserted through the slot 19 f in the hinge element 19 b. When theunderlay cover 14 rotates, the rod hinge element 17 b rotates within theslotted hinge element 19 b, and the hemispherical tip portions 17 d and17 e rotate within the sockets 19 d and 19 e, respectively.

[0039] The case 10 may be orientated in three different supportpositions after the wire type lock member has been detached and thelatches 16 have been opened. In accordance with this invention, eachcover member 12, 14 is manually rotated through an arc of at least 270°.This enables the case 10 to be rested on a flat, substantially planarsupport surface 50 in anyone of the three different positions; an easelposition shown in FIG. 2, a display position shown in FIG. 3, and atable position shown in FIG. 4. FIG. 2A shows the cover members 12, 14rotated from a closed position as shown in FIG. 1, where the covermembers 12, 14 cover the storage side 24 of the case 10, to a supportposition, where the cover members 12, 14 is completely opened andprojects rearwardly from the base side 22 to form an angle A of 90° orless with the base side.

[0040]FIG. 2 illustrates one cover member, namely, the cover member 12,completely opened and rotated into the easel support position, such thatthe cover member 12 supports the tray body 20 so that it is positionedin an upright state. The cover member 12 has a face side 12 e that facesthe storage side 24 of the tray body 20 when closed, and faces and restsupon a planar support surface 50 when in the first support position,referred to herein as the easel support position. The tray body 20 issupported by the overlay cover member 12, such that a hinged edge E1 isparallel to the support surface 50. The underlay cover member 14 mayalso be used to support the tray body 20 by simply inverting the case 10with the cover member 14 completely opened.

[0041]FIG. 3 illustrates the two cover members 12, 14 completely openedand both rotated into the display support position, such that an edge 14c, 12 c (FIG. 1) of each cover member 12, 14 rests on the supportsurface 50. An edge 26 a of the tray body 20 also rests on the supportsurface 50, and the tray body 20 is positioned in an upright position.

[0042]FIG. 4 illustrates the two cover members 12, 14 completely openedand both rotated into the table support position, such that opposingedges 12 f, 14 f of each cover member 12, 14 is in contact with thesupport surface 50, and the tray body 20 is positioned in an elevated,substantially horizontal position above the support surface.

[0043]FIGS. 9, 10 and 11 illustrate a removable support insert 30 thatmay be used to support the tool case 10 for display without detachingthe wire type lock member. Typically, the insert 30 is L-shaped having apair of legs at substantially a right angle. It is also contemplatedthat the insert 30 may other shapes, such as, T-shaped. The insert 30 iscoupled to the tray body 20 by inserting a leg into a slot 36 located onthe tray body 20. Typically the slot 20 is located near one of the edges26 a, 26 b, 28 a, 28 b of the tray body 20. The insert 30 isfrictionally secure in the slot 36, and is removed by sliding the insert30 outward. With the insert 30 inserted, the insert serves as a basethat rests upon the support surface 50 to orient the case 10 upright asshown in FIG. 9.

Alternative Embodiments of This Invention

[0044] The general shape of the tool case may take many forms. A toolcase having rectangular shaped cover members and main body has beendiscussed. The shape of the cover members and main body may take othershapes, such as, circular, oval, diamond and hexagonal. FIGS. 12, 13 and14 illustrate a tool case 70 having hexagonal cover members 72, 74, anda hexagonal main body 76. L-shaped inserts 30, 31 may be inserted intoslots 77, 78. The inserts 30, 31 enable the tool case 70 to rest uprighton a supporting surface. A pair of latches 16 may be used to secure thecover members 72, 74 in a closed position. FIG. 15 illustrates a tool 80case that has the general shape of a cylinder. It also includessemi-circular cover members 80 a and 80 b attached by hinges 81 and 82to a circular shaped main body 86. These two alternate embodimentsfunction in substantially the same manner as illustrated in connectionwith the first embodiment, the tool case 10, to enable these cases tohave:

[0045] (1) An easel orientation support position where one of the covermembers projects outward from the base side and the face surface of thisone cover member rests on the planar support surface.

[0046] (2) A display orientation support position where one set of edgesof both cover member rests on the planar support.

[0047] (3) A table orientation support position where another set ofedges of both cover member rests on the planar support.
